TELESCOPE SITE HAS 300 CLEAR NIGHTS A YEAR

The giant dome for the McDonald Observatory pictured on the front cover of this week’s Science News Letter is now completed and ready for the installation of its huge, 80-inch telescope as soon as the instrument has been ground.

Mount Locke, in Texas, was selected as the site for the new telescope because a survey showed that the location is blessed with more than 300 clear nights a year on which astronomers will be able to watch the stars.
